The answer to 'countertop dirty' is that there are several common causes for a dirty countertop, including spills, stains, buildup of grime and residue, and improper cleaning. Symptoms may include visible stains, a dull or discolored appearance, and a rough or sticky surface texture.
For most minor countertop cleaning issues, a DIY solution is often effective. Start by wiping up any spills immediately and using a mild soap and water or a specialized countertop cleaner. Avoid abrasive cleaners or scrubbing pads, which can damage the surface. If the countertop is heavily soiled or the stains won't come out, it may be time to call in a professional cleaning service.
